← GeographyWhich amplified effect appears when thawing permafrost triggers solifluction?
A)Increased global methane concentration✓
B)Stabilization of high-latitude slopes
C)Reduced river sediment transportation
D)Decreased albedo from exposed bedrock
💡 Explanation
Increased methane concentration occurs, because increased temperature drives solifluction of organic-rich permafrost, releasing methane through microbial decomposition; therefore, rather than stabilizing slopes, solifluction accelerates slope instability and greenhouse gas emissions. The mechanism at play is a positive feedback loop.
